cv.error must be wrong #10

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago

What steps will reproduce the problem?
1. Fit model using cv.folds > 1
2. Install older version from CRAN and refit
3. Look at gbm.perf

What is the expected output? What do you see instead?
The plots should be similar

I think cv.error is being wrongly scaled. If so, the 'best' number of trees is 
still being used.
